Motor Aspects of Lateralization: Evidence for Evaluation of the Hypotheses of Chapter 8
Published in Robert Miller, Axonal Conduction Time and Human Cerebral Laterality, 2019
Ideational apraxia is a motor disorder at a higher level than ideomotor apraxia. Patients typically are impaired in sequencing actions requiring the use of various objects in the correct order and sequence, in order to achieve a goal. According to Poeck (1986)this disorder is rare, but, when it occurs is chiefly in cases of lesions of the language-dominant hemisphere.
Signs and Symptoms in Psychiatry
Published in Mohamed Ahmed Abd El-Hay, Essentials of Psychiatric Assessment, 2018
Ideational apraxia: the inability to perform an organized motor sequence, although the individual components can be performed separately. It is possibly due to fear about how to carry out a movement, but once the patient has been cued he/she produces the correct response. It could be tested by asking the patient to show how he/she folds a letter, places it in an envelope, and then seals and stamps the envelope; lighting a candle with matches; or making a cup of coffee. To the observer, the patient gives the appearance of being naïve or unfamiliar with the sequence of activities that should occur. These patients fail to use everyday objects correctly. Ideational apraxia affects the limbs on both sides. It results from lesions in the region of the left angular gyrus.
Disorders of Sensation, Motion, and Body Schema

Ideational apraxia: Semantic (impaired gesture comprehension and production of familiar gestures), and procedural (impaired production of familiar gestures). This is a failure of the sequence, creating inability to carry out a task automatically to achieve a goal. For example, sealing an envelope before inserting the letter.

Apraxia has been attributed to a conceptual or production problem when performing a desired action (13–15). The conceptual component of complex movements involves knowledge of action sequences and/or knowledge of tool use with the deficit in these commonly known as ideational apraxia. Ideomotor apraxia is a deficit in the production of both known, meaningful gestures (including transitive movements that involve tool use, or intransitive movements such as communication gestures) and novel, meaningless gestures. Ideomotor Apraxia is usually diagnosed by asking people to perform meaningful or meaningless gestures either by imitating the examiner (i.e. using visual cues) or pantomiming (i.e. following verbal commands).

Apraxia occurs when CNS lesions damage the anterior cingulate, corpus callosum, and/or posterior parietal cortex, core tractus solitaries, hypothalamus, amygdala, insular cortex, and anterior cingulate cortex and parietofrontal pathways. In the case of ideomotor apraxia, patients cannot conduct movements purposefully. Individuals with apraxia are able to do automatic movements. For instance, patients with apraxia can brush their teeth. However, they cannot carry out this task when asked to do a different movement with the toothbrush. Furthermore, in the case of ideational apraxia, patients fail to complete automatic movements [7,8].
The relationship between early post-stroke cognition and longer term activities and participation: A systematic review
Published in Neuropsychological Rehabilitation, 2020
Apraxia: In one study, performance on a task of ideational apraxia predicted activities and participation but this study did not meet our definition of well-controlled (Sveen et al., 1996). In this study, ideomotor apraxia predicted participants’ ability to use the telephone, to handle finances, and to administer medication but not scores on validated outcome measures (Sveen et al., 1996).
